Abstract:
The forming and activation of the conductive films are studied experimentally. The power supply,a peak-to-peak 30 V triangle profile voltage,is applied to three kinds of conductive films that contain 0.25%,0.5%,and 1% of palladium respectively. In the experiments we contrasted the values of related parameter in different conditions,observed the lumi nous spots on the anode panel,dealt with and analyzed the related data,and compared the positions and the amount of the luminous spots. We have gotten the conclusion that there is a threshold value Uth. The emission current Ie will increase rapidly when the device voltage Uf is greater than Uth. And the emission current Ie could be controlled by the device voltage Uf.The positions of the luminous spots on the anode panel are related with the device voltage Uf.
